The innovation of democracy revolutionized political theory. It discerned that everybody is more capable of deciding what is best for everybody than some quantity of persons less than everybody. I agree.
Where I disagree with democracy, whether representative or direct, lies in the right of each citizen to cast a vote determining what is best for everybody else. If a king shouldn’t have that power, why should I? Why am I the best determinant of my neighbor’s best interest, and not my neighbor him or herself?
